While neutrons are also found in the nucleus of atoms and have no net charge, they are made up of quarks, which carry fractional charges. Therefore, neutrons are not fundamental particles like neutrinos.
Here's a breakdown:
* Neutrinos: These are fundamental particles, meaning they are not made up of smaller particles. They have extremely small mass and interact very weakly with matter, making them incredibly difficult to detect.
* Neutrons: These are composite particles made up of three quarks (one up quark and two down quarks). While the net charge of a neutron is zero, the individual quarks carry fractional charges that cancel each other out.
Therefore, the only subatomic particle that is truly neutral and fundamental is the neutrino.
